The BDS (Broadcast Data Systems) system detects each time a record that has been specially coded for BDS recognition. BDS reports the real number of radio spins a record gets. Using a unique computer technology, BDS monitors radio and television broadcasts, keeping track of songs and commercials as they are being aired. Thru the BDS network, record executives, programmers and advertisers can access detailed information about the exact time, date, and size of audience associated with airplay on over 560 radio and 500 TV stations.
Also your song has to be on for at least 20 seconds (I believe) in order to be tracked, so if a DJ just scratches 10 seconds of your song into a mix, it may not pick up.
BDS is really good to see what stations are playing your shit and who is just taking your money (aka payola....illegal, but it's being done everyday).
Here is the address to get your music listed with BDS:
For BDS (tracks radio air play), send a copy of the song you want "fingerprinted." It must be the exact version you intend radio to play. Send a note listing the name of the songs (A side and B side), the name of your record label, and the type of music that it is.

8100 NW 101st Terrace
Kansas City, MO 64153
816.891.1010
It is free to have your music listed with BDS, but they charge (hella amount) to retrieve the data. All major labels subscribe to both BDS and SoundScan. Got a friend at a label who can pull your info for free?
So unless you are really moving some units or you know you are gettin' some major spins, get BDS, but if you are on the underground trying to get shit crackin' leave it alone.
